01 The Fremont in Desolation Canyon
Over 300 archaeological sites from Sand Wash to Swasey’s.
The earliest occupants were nomadic Archaic peoples who hunted with the atlatl. By about A.D. 600, the first Fremont farmers arrived. Most evidence points to small family groups that moved frequently between scattered fields. By A.D. 1000, population peaked during higher rainfall. By A.D. 1150, persistent droughts forced most to leave.

Respect Archaeological Sites
Never touch or deface rock art. Do not trace images, apply chalk or water, or remove artifacts. Federal law (ARPA) penalties include fines up to $100,000.
03 Granaries: Hidden Architecture
Fremont storage facilities in cliff overhangs using stone slabs, mud mortar, and wood. Not residences. Their abundance supports the theory of seasonal occupation.
04 Petroglyphs vs. Pictographs
Know the Difference
Petroglyphs: Pecked into rock, removing dark desert varnish. The most common form in Desolation Canyon.
Pictographs: Painted using mineral pigments. Less common, more fragile.
Fremont-style features: trapezoidal body shapes, elaborate headdresses, shield figures, bighorn sheep motifs.
